yTo all whom 'it may concern:

`useful Improvement in Anticreepers, of

which the following is a full, clear, concise, and exact description.

My invention relates to anti-creepers or rail anchors more particularly of the type wherein a transverse member is held to one side of the rail base by a jaw thereon which fits over saidbase and is held at the other end by a clip or dog in the general form of a jaw which fits beneath the transverse member and over the side of therail base to hold said member up against the bottom of the rail base.

Anti-Creepers constructed along such lines,

when put -in service have, in many cases,

proved unsatisfactory due to the stretchingv or slight elongation of the dog or lock as it is being forced into position. The result of such elongation is that the end of the anchor lengaged by said dog is not held to the rail base as firmly as Imght be desired, thereby diminishing the effectiveness of the anticreeperlasa whole. y p f The object of the present invention is vto provide an improved anti-creeper in which this .objection is overcome. Twoembodiments of the invention are shown in the f accompanying drawings in which said object is attained by a resilient structure which yieldingly engages the rail base, whereby when the parts are forced into position, the transverse member yields somewhat instead of the' dog, the effectiveness of the anchor as a whole bein unimpaired by said yielding action. Sai v other structures however,"which fall within the scope of the invention. y

Figure 1 of the drawings is a rear eleva-` tion of the rail anchor, a portion of the rail being shown in section.

. Fig. 2 is a. top plan view of the base of the rail with the rail anchor thereon.

Fi 3 is a rear elevation of a rail anchor the parts show1ng the"relative position of w the rail as the anchor is being applied to base. l d Fig. ,4 is a perspective view of the clip or dog. .v D

Fig. 5 is la perspective view of the transverse mem r.

objectmay be attained by 4 whereby a shoulder 5 is formed. The` lati eral projection is bent down to. form a tieabutting flange 6 having an extension 7 thereon, which is bent at right angles to form a reinforcing flange which is arranged to bear upwardlyv against the main body of said transverse member. The other end of said member is bent to form a downward extension 9 which is provided with a notch 10, which notch is adapted to receive the dog 2. Said dog is notched out to form what is in effect a jaw. The upper surface 11 yofsaid jaw is arranged to bear'against the upper side of theI rail base. The lower surface thereof is preferably provided with a notch 12 arranged to fit within the notch 10 in the transverse member. The vertical wall 13 of said jaw is arranged to contact with the vertical edge of the rail base.

To assemble they device on the rail, the transverse member 1 is placed thereon in approXimately the position shown in Fig.. 3 with the rail flange projecting as far as possible into the opening inbthe 3 aw 3. In this osition, the downward extension 9 projects eyond the other side of the rail base. The transverse member 1 is curved or crowned somewhat bein in contact with the base of the rail for on y a portion of its length, as shown in Fig. 3, thereby providing a clear ance between itself and the rail base near the opposite sides of the latter. In this position the dog 2 may be hooked under the enn tension 9y and'litted 'yer the top of the base Bange as shown in said Fig. 3. The dog and the transverse member are then forced to "the left either by hammering them or applying forcein any suitable manner. During such movement the inclined surface l1 of the dog rides upwardly along thev inclined top of the rail base, thereby raising the notched portion y12 and also the downward extension 9 of the transversey member which is engaged therewith. Simultaneously, the

jaw 3 moves away from the opposite side of the rail base. The movement of the device as a whole to the left puts the transverse member l under increasing tension as said movement continues. Bythe time the vertical wall 13 of the dog comes in contact with the adjacent vertical wall ofithe rail base, the member 1 is under considerable tension, and simultaright hand end of the transverse member is firmly clamped against the rail base by the dog 2, and the left hand end thereof is held in rm frictional engagement with the top of the rail base due to the downward pressure of the extension 4 thereon. The rail anchor is so positioned that its downwardly extending flange 6 bears against the cross tie 14 in the usual manner, thereby transmitting thereto the creeping thrust of the rail 15 which is supported on said tie.

The creeping of the rail is checked by the rail anchor but the initial movement of the rail may tiltv the dog 2 somewhat out of-a vertical plane. However, such tilting action serves only to further increase the grip of the rail anchor on the rail base. It will be seen that the grip is thus increased upon of traiiic, in which case rearward movement v of the anti-Creeper is resisted byrthe ballast in which the iange 6 is embedded. Such rearward movement is resisted more particularly in winter when the ballast'may be frozent into a solid mass.

If it becomes necessary to remove the rail anchor, such 'removal may be eected by forcing up the left hand end of the transversemember 1 and driving said member to the right to return the parts tothe position shown in Fig. 3, whereupon the dog and transverse member may be separated from each other and both parts readily removed from the rail.

The anti-creeper shown in Fig. 7 is similar in most respects to the one previously described. It consists of a transverse member 14 havin a jaw 15 which fits over one side of the rai base, the downwardly extending projection 16 at the other end having a notch which coperates with the dog 17, The lat- .ter has a notch 18 which coperates with the notch in the downward projection 16, and

has an inclined surface 19 which guides the latter as hereinafter explained. The rail base fits within a notch or recess 20 whereby the rail is gripped both above and below and any tilting action results in increasing the gri The dog is first applied tothe rail an held against movement by a bar 21 for example, after which the transverse member is driven into position by a man1 22. The downward extension 16 rides along the inclined surface 19 until the notch therein snaps into the notch 18, whereupon the parts are locked against movement.

It is apparent that the type of dog described with the second form of device may be used with the iirstform of vdevice if desired, and vice-versa. In general the invention is not limited to the embodiments thereof illustrated in the accompanying drawings as other forms may be devised which fall within the scope of the claims.

Having thus described my invention, what I deslrel to secure by Letters Patent of the United States is:

1. A rail anchor comprising a transverse member normally curved downwardly at opposite ends, a jaw integral with one end thereof, and a do other end upwar ly against the rail base when said member is moved transversely thereof ,tol position the parts thereon.

2. A rail anchor comprising a transverse member beneath the rail base, means at one end thereof for holding said end to the rail, means at the other end thereof for holdin said other end to the rail, said other end normally tending to spring away from the rail base whereby it is maintained under tenslon by said second means, the ositioning of said vsecond means being e ected by lateral movement of said transverse member across the rail base, and means associated with saiddrst means for. preventing return movement.

3. A rail anchor comprising a transverse member having a jaw at one end, and a dog for holding the other end of said member to the rail' base, said dog bein applied to the latter when the opposite si e of the rail base is received well within said jaw, the final positioning of said parts providing a clearance between the vertical wall of said jaw and the adjacent edge of the rail base.

4. A rail anchor comprising a 'transverse member having a jaw at one end, a dog for holding the other end of said member to the rail base, said dog being applied to the latter when the opposite side of the rail base is received well within said jaw, the final positioning of said parts providing a clearance between the vertical wall of said jaw and the adjacent edge of the rail base, and means for maintainlng said parts in said latter position.

5. A rail anchor comprising a transverse member curved downwardly at opposite ends, a jaw integral with one end thereof, a cli arranged to force said other end upwa y against the rail base when said member is moved transversely with respect to arranged to draw said thedrail, and aishoulder on theA up er side of sai tension at the other end thereof, a clip engaging said downward extension and one Side of the rail base, the other side of said rail base being engaged by said offset extension.

7. A rail anchor comprising a clip having an inclinedV surface -to engage the inclined surface ofthe rail base near one edge thereof, and also having a horizontal surface, and a vertical surface, a transverse member one endof which has positive engagement with said horizontal surface, the

other end of said member being curved around to fit over the other opposite inclined side of said rail base, thereb forming a' jaw, there being a clearance etween said jaw and the adjacent edge .of the rail base when the vertical edge of said clip is in engagement with the adjacent side of the rail base, said transverse member beingy under tension, whereby said jaw bears downwardly against the top of the rail base.

8. A rail anchor consisting of a transverse member having one'end doubled back to form a jaw, the end of said jaw being offset whereby a shoulder is provided, an integral downward extension on said member forming a tie-abutting flange and having a portion bent rearwardly to form a brace, the other end of said member being bentdownwardly and havin a notch in its lower eX- tremity,` a clip in,t e form 'of a jaw having a notch in the lower wall thereof fitting said first notch and having .an upper wall engaging said upper side of the rail base, said transverse member being maintained under tension b said jaw and clip.

9. A bia ting flange is formed,' said projection having a lateral extension from which a brace is formed, said strip being notched at one 10. A blank fora rail anchor consisting of a strip of spring steel having an intermediate projection from which a tie-abutting fiange is formed, said projection having a lateral extension from which a brace is formed.

11. A railanchor comprising a transverse member normally curved downwardly at opposite ends, a jaw integral with one end nk for a rail anchor consisting of a strip of sprlng steel having an inter- 4mediate projection from which a tie-abutthereof, a dog arranged to draw said other i end upwardly against the rail baseA when said member is moved transversely thereof to position the parts thereon, and means to maintain said parts in position.

In witness whereof, I hereunto subscribe my name this 6th day of June A. D., 1916.
